A new air conditioning system can completely transform your home’s comfort, making those warm summer days far more enjoyable. However, when you’re planning an installation, one of the most common questions is how long the process actually takes. While the average installation can be completed in one to three days, the exact duration depends on several factors including the type of system, property layout, and any preparation required. By understanding what’s involved, you can plan ahead, reduce disruption, and ensure your installation goes smoothly from start to finish.
Air Conditioning Installation Process
The Pre-Installation Assessment
Before installation day, your engineer will visit your property to inspect your space, measure the area, and confirm the best location for both the indoor and outdoor units. They’ll also discuss how you use each room and assess your electrical system’s capacity. This stage ensures that your new air conditioner not only fits your home but performs to its full potential.
The Installation Timeline
Single-Split Systems
Single-split systems are the simplest and quickest type to install, featuring one indoor unit paired with one outdoor condenser. These systems are ideal for individual rooms or smaller spaces and can often be completed within a single day. The process involves mounting the units, drilling a small hole for the pipework, and connecting the electrical wiring and refrigerant lines. Once installed, the engineer completes safety checks, pressure testing, and a final system run to confirm everything is operating efficiently, allowing you to enjoy instant cooling comfort.
Multi-Split Systems
Multi-split systems offer greater flexibility and are designed to cool multiple rooms at once using several indoor units connected to a single outdoor unit. Because of the added pipework and wiring, installation typically takes two to three days. Engineers plan and route refrigerant and drainage lines between each unit, ensuring all pipework is neatly hidden within ceilings or walls. The extra time ensures a clean finish and balanced cooling across every room, giving you precise temperature control throughout your home.
Ducted Systems
Ducted systems are the most comprehensive option and can take up to four days or longer to install. These systems deliver air through concealed ductwork in ceilings or loft spaces, providing whole-home comfort with a sleek, invisible finish. Installation involves fitting vents, connecting ducts to a central indoor unit, and carefully balancing airflow across all rooms. While more time-intensive, a ducted setup provides the most discreet and energy-efficient cooling system available, blending powerful performance with modern design.
Electrical and Structural Work
Sometimes, installations take longer because of property-specific requirements. For example, older homes may need upgraded wiring or a new circuit to safely power the system. In other cases, external walls might require reinforcement to securely mount the outdoor unit. Addressing these needs during installation ensures safety, reliability, and longevity.
Testing and Commissioning
Once everything is installed, your engineer will test the system thoroughly. This includes pressure testing, leak detection, and checking refrigerant levels. They’ll also verify the system’s electrical connections, measure airflow, and ensure every component functions correctly. Commissioning is the final and most important stage, as it ensures your air conditioner runs efficiently from day one.
Handover and Homeowner Guidance
After the final checks, your engineer will walk you through your new system, showing you how to use the controls, change settings, and maintain the unit. You’ll also receive maintenance tips, such as how often to clean the filters and when to book a service. This handover ensures you can confidently manage your system and keep it performing at its best.
